語法拓展
一、一般現在時中have的用法
一般現在時的謂語動詞可以由be動詞（前面已學過）或實義動詞來充當。今天我們重點學習含有實義動詞的一般現在時。（主要介紹have的用法）。
1.定義：一般現在時可以用來表示現在的狀況，主語的性格、能力以及經常性或習慣性的動作。
have意為“有”，表示所屬關系，有人稱和數的變化，其主語一般是人，有時可以是物。
（1）have用于復數名詞，第一二人稱單、復數或第三人稱復數作主語的句子中，has為have的第三人稱單數形式，用于不可數名詞、可數名詞單數或第三人稱單數作主語的句子之中。
I have an orange.
Tom has a friend.
（2）have/has作謂語時的句型轉換。
①否定句式：主語+don’t/doesn’t+have...
I don’t have an eraser.
He doesn’t have a tennis bat.
②一般疑問句：Do/Does+主語+have...?
肯定答語：Yes,主語+do/does.
否定回答：No,主語+don’t/doesn’t.
—Do you have a bike? —Yes,I do./No,I don’t.
—Does she have a tennis ball? —Yes,she does./No,she doesn’t.
二、并列連詞and和but的用法
兩詞都為并列連詞，用來連接兩個單詞或句子，使其前后的詞、短語或句子有順承、對立或對照性的關系。
（1）but意為“但是；然而”。表示對立或對照性。
He has an apple,but I don’t have one.
（2）and意為“和……；以及……”。表示并列、反復或承接關系。
Jenny and Alice are my friends.
They talk and talk.
